Macro trillium_channels::event

macro_rules! event {
    ($topic:expr, $event:expr) => { ... };
    ($topic:expr, $event:expr, $($json:tt)+) => { ... };
}

This macro provides a convenient constructor for a ChannelEvent. It is called with a topic, an event, and an optional inline json payload.

let event = trillium_channels::event!("some:topic", "some:event");
assert_eq!(event.topic(), "some:topic");
assert_eq!(event.event(), "some:event");
assert_eq!(serde_json::to_string(event.payload()).unwrap(), "{}");


let event = trillium_channels::event!("some:topic", "some:event", { "payload": ["any", "json"] });
assert_eq!(event.topic(), "some:topic");
assert_eq!(event.event(), "some:event");
assert_eq!(serde_json::to_string(event.payload()).unwrap(), r#"{"payload":["any","json"]}"#);
